Product Overview

British precision. Compact power. Versatile compatibility.

The Hope RX2 is a two‑piston flat‑mount brake caliper engineered specifically for road and gravel bikes. Designed as the compact sibling to Hope's renowned four‑piston RX4, the RX2 delivers exceptional braking performance in a slimmer package—ideal for frames with limited rear triangle clearance and riders who prefer a lighter, more nuanced feel.

CNC‑machined from a single block of 2014 T6 aluminium in Hope's UK factory, every RX2 caliper embodies the brand's obsession with precision engineering and unmistakable style. Available in two distinct versions to suit your drivetrain, the RX2 brings World‑class stopping power to any build.

Two Versions – One Caliper



Version Fluid Compatibility
DOT (DOT) DOT 4 / DOT 5.1 SRAM road hydraulic systems
Mineral Oil (MIN) Mineral Oil Shimano & Campagnolo road hydraulic systems

⚠️ Choose the correct version for your groupset—DOT fluid and mineral oil are not interchangeable.
